1. Limited Control Over Keyword Targeting

Unlike Search campaigns, where advertisers can manually add negative keywords at the campaign or ad group level, Performance Max operates with Google’s AI-driven automation. This often meant ads could show for irrelevant queries, with little control over exclusions.

2. Complex Exclusion Process

Until now, adding negative keywords to Performance Max campaigns required advertisers to go through their Google Ads account manager, a process that could be time-consuming and inconsistent. Advertisers had to rely on external support for updates and changes without direct access.

3. Wasted Ad Spend

The inability to exclude irrelevant search terms led to ad budgets spent on clicks that were unlikely to convert. For example, a premium fashion retailer might have their ads triggered by searches for “cheap” or “discount” products, attracting the wrong audience and decreasing ROI.

4. Lack of Visibility

Performance Max campaigns aggregate data across multiple channels (Search, Display, YouTube, etc.), making it difficult to pinpoint where wasted spend occurs. The absence of negative keyword control compounded this issue, leaving advertisers with limited insights and reactive strategies.

5. Brand Safety Concerns

Without negative keyword exclusions, brands risked their ads appearing associated with inappropriate or irrelevant content, potentially harming brand reputation and trust. Industries with strict compliance requirements, such as finance or healthcare, found this especially challenging.
